hover effect in product list

Hi,

That effect is added by the template we use on our demo website:
www.joomlashine.com/joomla-templates/jsn-glass.html
It's done with a bunch of CSS at the beginning of the file demo.hikashop.com/templates/jsn_glass_pr...jsn_ext_hikashop.css and a slight modification of the listing_img_title view file to add the div with the class product-content.
